The clinical profile for apomorphine sublingual (SL), a new centrally active agent for the management of the erectile dysfunction (ED) patient, is described in this article. Apomorphine SL is shown to be rapid in onset (71% of patients within 20 min) with a consistent, predictable response that is independent of severity (mild, moderate or severe), the underlying aetiology or the presence of significant co-morbidities (coronary artery disease, hypertension, etc). Importantly, there is also consistent long-term clinical benefit ( > 90% of attempts being successful over 18 months), for patients who respond to therapy and a benign side effect profile ( < 13.4% patients with adverse events). This formulation of apomorphine has a speed of onset and overall clinical profile that may offer particular advantages to the patient in terms of spontaneity and predictability of response. ED is a complex disease of varying aetiologies and severities often associated with a number of co-morbidities that require diverse solutions. Given the need for customisation of therapy to individual patient needs, the clinical profile of apomorphine SL would indicate that it will make a most welcome addition to the physician's armamentarium against ED.
